To all arlfomz't may comm/m:

Be it known that I, Oris E. DINGLEY, a citizen ofthe United States, residing at l"Vest Farmington, in the county of Franklin, in the State of Maine, have invented a vcertain new and useful Improvement in De mountable 'Rims for Veln'cle-lllieels., of

fellies of wheels of automobiles and otherv vehicles; my improved construction being such that a disabled tire may be removed and a new tire substituted therefor in two minutes, or less time, without the detachment of nuts or bolts, as'I have explained in detail hereinafter. i

My invent-ion is .illustrated in the annexed drawing, Figure 1 being ra side view of'a wheel equipped with my present improved demountable rim mechanism. Fig. 2 is a relatively enlarged, transverse sectional view taken on the line 2-2 of said Fig. l.v

Fig. 3 shows two side views of a thimble or bushing 25 which is fixed in the wooden felly of the wheel and is threadedinternally to receive a screw which, when the several parts of my as a bolt to prevent the accidental separation of the tire-supporting rim and the wooden felly of the wheel. y

In Fig. .2 the said bushing and screware shown assembled, mainly in central longitudinal section. Fig. 4E is an inner side view of a portion of the tire-supporting rim show`- one of the integral 'sockets adapted to receive the end of one of the bolts which I have mentioned above.

Referring to these drawings, the numeral 20 indicates the felly of a lvehicle wheel, and 21. denotes the detachable metal rimon which the tire proper is mounted. said tire being indicated by the dotted circle in Fig. l. My present invention, however, has no relation tothe manner of mounting the rubber tire on the said rim; said inventionre' latihg only to the means for 'detachably securing the rim to the fixed felly of thevehicle wheel. On the inner face ofthe rim 21 are hub-like projections ree'ends of screws 24' device are assembled, operates i sary 22' (as here shown) which are chambered as at 23 to receive. thethat 'are located in 'v bushings 25, which bushings arej ixedly forced into lthe wooden felly: each bushing being, preferably. formed with an enlarged outer end portion, as at 25a, to limit the entrance of the bushing` in the felly. and also with one or more fins 25h which prevent the rotation of the bushing in said fellv after the bushing has been forced home'in the felly. The bushings 25 are arranged in radial relation to the wheel center and are of such number, and so spaced apart, that they register withthe hubs Q2 on the inner side of the rim 21 and so that` when the screws 24 are'screw'ed home. the outer end portion of each screw will enter the opening, or socket. Q3 in one of the hubs thus providing a plurality of bolt fastenings between the tire 11m and the wheel felly.

of spokes, .that is to say. if the wheel has twelve spokes. I provide six of the described screw bolts although the number of bolts is not arbitrarily fixed by me.

Y The numeral 2l denotes the head of the screw 2i and the numeral '26 identifies a spring washer located on the body of the" screw just under the head Qta. 4The rim 2l and the felly 2O are formed with registering,

holes to receive the customary valve stem 2T when the parts are assembled and. at a point on the fellv. approximately opposite the said valve hole. I fasten guide plates QS-QQ at the opposite sides of one of the bushings 25.

In the operation of mount-ing a'tire-rim on a wheel. the bolts are first unscrewe-d,

as seen in full lines ,in Fig. 4. That portion' 'The several bolts 2l are then screwed home and .it will now 'be understood that the rim Y By preference I "provide such bolts between every other pair 21 will be securely fastened to the wheel i felly until such timev as it-niay be desired to remove the said rim when itis'only neeesadopted a four-tothe? .have vintentionally to unscreweachbolt rasin le turn as I Vwithdrawn from the sockets 23,' and fsofthat bushings 25'. ,f nim-n thus-beseeifttaethee are no detached bolts,niits, or other parts to be lost, or dropped in the dirtl` during the operation of removing an old tire and re- )lacing it with a new one. s an additional support for the tire rim 21 lumps 30 may be fixed in the perimeter of the wooden elly 20 between the bolts :24:A although such additional supportsare not regarded by me as absolutely necessary. A

My described construction renders it possible .and convenient to make a quick-shift whenever it is necessary lor desirable to change tires. and the change may be readily effected by anyone who is not at all familiar with mechanics or -mechanical devices or 0 a rim, a felly, threaded bushings mounted in said l telly and having outwardly flared ends forming bearing surfaces flush with the. oi tlerpe-1 riphery of said felly, a plurality of inwaidly projecting hub-like extensions formed in- 'tegialwith the inner periphery of saidrim and resting onsaid bearing surfaces, said extensions being provided with inwardly I facing sockets, guide plates fastened-on said felly surrounding one of said bushings and a plurality of inteinhlly adapted to receive one of said hub-like eX- tensions therein to position all of said sockets in registration with the bores of said bushings, and a plurality'ofI bolts engaged with-said bushings and having unthreaded outer ends adapted to extend beyond said telly and be loosely received in said sockets.
